Tight carrier first hundred
Reviewed on April 28, 2026Verified with Build

BCG is built right, lockup and ejection are correct. only quirk is the carrier was tight in an aero upper for the first 100 rds, some break in friction. now after 400 rds it glides clean. likely tighter clearance than other BCGs i have run

Reviewed on April 18, 2026Verified with Build

full auto profile carrier, phosphate finish, C158 bolt. machining is what you expect from a PSA premium line. lockup on my barrel was correct, headspace gauges fell where they should. for the price you cant beat the QC
